An application that you are managing has EC2 instances & Dynamo OB tables deployed to several AWSRegions in order to monitor the performance of the application globally, you would like to see two graphs:
1) Avg CPU Utilization across all EC2 instances
2) Number of Throttled Requests for all DynamoDB tables.
How can you accomplish this?

A.
Tag your resources with the application name, and select the tag name as the dimension in the Cloudwatch
Management console to view the respective graphs

B.
Use the Cloud Watch CLI tools to pull the respective metrics from each regional endpoint Aggregate the
data offline & store it for graphing in CloudWatch.

C.
Add SNMP traps to each instance and DynamoDB table Leverage a central monitoring server to capture
data from each instance and table Put the aggregate data into Cloud Watch for graphing.

D.
Add a CloudWatch agent to each instance and attach one to each DynamoDB table. When configuring the
agent set the appropriate application name & view the graphs in CloudWatch.
